Abstract
A direct current (DC) uninterruptible power supply (UPS) configured as an intrinsic power transfer switch is provided. The DC UPS includes first and second inputs. First and second rectifiers are coupled to the first and second inputs. A common node is coupled to the first and second rectifiers. At least one DC output is coupled to the common node. The at least one DC output is adapted for connection to at least one electrical load. The first input is adapted for connection to a first electrical service, and the second input is adapted for connection to a second electrical service. The DC UPS continues to supply power to the at least one electrical load in the event of a loss of either the first or second electrical services.
